Organizations refer to collaborative Accounts comprising multiple Users. They provide an environment for users to collaborate together, and to mutually share entities under the respect of a set of permissions.
The various users belonging to an Organization can have different Roles attributed to them, as explained here.
The Organization's members can be grouped together into Teams, which are the object of a separate discussion.
The list of all users and entities contained in an organization and its Teams can be viewed through the corresponding components of the User Interface.
Administrative actions which may need to be performed within an Organization are reviewed in a dedicated section.
